Macbook Pro 17" — new akku LMP not load

..For a time some years ago the OWC (other world computing) company

showed more than one means to calibrate a portable Mac battery onsite.

Here's a link to page that shows/tells process for older version of calibration.

NewerTech - Older Portable Mac Battery Calibration Instructions:

https://eshop.macsales.com/Reviews/Framework.cfm?page=hardwareandnews/newerbatteries/newerbatteryconditioning.html

These instructions worked OK, with certain known issues back in the day

and their suggestion (for early newertech battery used in older portables)

was to be repeated at some point. Later instructions avoided this aspect.

The battery you received might or might not be suited for use now; date

of manufacture being two+ years, could be an issue. ~ These might not

honor an old guarantee; most genuine batteries included 1-year warranty.

Makers of Chinese batteries are unlikely imports from outside CH regions.

A PDF for Battery Conditioning for older design Mac batteries shows more:

Instructions within this PDF points to helpful further instruction with

extra additional information/links from portal, how to Reset the SMC.

Reset the SMC of your Mac - Apple Support

NewerTech's PDF has instructions now lacking from other official sources.

Those might be place to start, after you determine battery warranty status.

[Original batteries changed over time, latest versions are 'internal' access.]

..These instructions could be useful, should the battery appear dead..

You are referring to the battery? Remember, these are worlwide forums and you posted in the English version and not everyone knows what an akku is. I am not familiar with LMP. In the US, the only reliable replacement batteries are sold by OWC (macsales.com). There are no OEM batteries available.

This is what I would have bought - the specs are slightly different:

And, a battery that is 2 years old?

Good luck from the US by way of Muenchen.
